Objective: To analyze and explore the correlation between enhanced recovery after surgery (ERAS) compliance and prognosis in patients undergoing minimally invasive gynecologic oncology surgery. Methods: Patients aged 18-74 years, BMI 18.5-30.0 kg/m2 and ASA physical status Ⅱ or Ⅲ who underwent elective minimally invasive gynecological tumor surgeries such as laparoscopic or robot-assisted hysterectomy with adnexectomy, hysterectomy with adnexectomy plus pelvic and/or para-aortic lymph node dissection between February 2020 and January 2024 were included. All patients followed a standardized 24-element ERAS protocol. Based on ERAS element compliance, patients were divided into a low-compliance group (group L, ≤ 70% compliance) and a high-compliance group (group H, > 70% compliance). The primary outcome was length of hospital stay (LOS). Secondary outcomes included 30-day postoperative complications and readmission rates, visual analog scale (VAS) pain scores at 6, 12, 24, 48, and 72 hours postoperatively, time to first oral intake, first flatus, and ambulation, intraoperative sufentanil consumption, and total fluid volume on postoperative day 1. Results: A total of 461 patients were enrolled, 227 patients in group L and 234 patients in group H. Compared to the group L, the group H had significantly shorter LOS, reduced intraoperative sufentanil use, lower 30-day complication rates, earlier resumption of oral intake, flatus, and ambulation, reduced and postoperative fluid volume (P < 0.05). Multivariate linear regression showed that after adjusting for covariates (age, preoperative coronary artery disease, albumin level, ASA physical status, surgical approach, and duration), ERAS compliance was independently associated with shorter LOS (β = -0.120, 95% CI -0.163 to -0.077, P < 0.001). No significant differences were observed in 30-day readmission rates or VAS pain scores between two groups. Conclusion: ERAS compliance is significantly correlated with postoperative outcomes in patients undergoing minimally invasive surgery for complex gynecological tumors. Higher ERAS compliance could reduce postoperative LOS and does not increase the risk of readmission within 30 days. |
